## Matlab双圆孔衍射仿真研究(菲涅尔和夫琅禾费衍射)

Title    The simulation of two-hole  Fresnel diffraction
Abstract
Optical diffraction experiment is a very important experiment, the diffraction phenomenon of light wave theory of light provides a strong evidence. Computer simulation of optical diffraction experiment not only in scientific and engineering computing has played an important role, but also in optics in the education sector also attracted wide attention. In this paper, based on the simulation of the system to achieve optical experiments using Matlab simulation theory and method, and optical diffraction experiment are presented in detail the simulation results. 源自!六%维^论*文`网www.lwfree.cn
This concept of the diffraction, and the difference between two kinds of diffraction experiments, light intensity distribution of programming principles and made a detailed and comprehensive introduction to, and use Matlab software to set up a typical mathematical model of diffraction, the diffraction intensity distribution of the programming operation, the diffraction experiment is simulated.  his paper respectively to Fresnel and Fraunhofer diffraction are simulated, and the simulation shows its hole, double hole, four hole diffraction pattern. From four Fresnel circular aperture diffraction patterns into our preliminary discuss a very important optical phenomena- optical vortex.
